2, 1932. I G. G. GILPIN ET AL 891223 Original Filed April 8, 1929Patented Dec. 20, 1932 UNITED STATES PATENT OFFICE GARTH G. GILPIN, OFRIVERSIDE, ANB ARTHUR E. SMALL, OF CHICAGO, ILLINOIS, ASSIGNORS,`BYMESNE ASSIGNMENTS, TO GENERAL STEEL CASTINGS CORPORATION, 0F GRANITECITY, ILLINOIS, A CORPORATION OF DELAVARE RAILWAY CAR Serial No.550,937.y

The invention relates to railway freight cars and particularly thatclass of equipment known as hopper cars7 wherein the lower portion ofthe car body comprises a plurality of hoppers. These hoppers aredisposedon the opposite sides of the center construction of the car andcross bearers are positioned between adjacent hoppers which are securedto the opposite side walls of the car and also connected to the centerconstruction. Some cars have just one cross bearer, while others have aplurality of cross bearers with hoppers disposed on bothV sides thereof.Other railway dump cars do not have any cross bearers but have arelatively long longitudinally extending door on each side of the centerconstruction. There are other numerous types of railway hopper carswhich need not be enumerated here and to which this invention willapply. n

In such type of cars the moisture in the lading, due torain, meltingsnow, thawing of the material, etc., accumulates adjacent the bottompart of the lading so that that part of the lading in Contact with thehoppers, center construction, cross bearers and other .associated partsbecomes wet and holds the moisture in contactV therewith causingexcessive corrosion when these parts are made of rolled steel,especially if such rolled steel parts have been deformed by pressing.tis common practice to use such doors for transporting coal and whenmoist coal, particularly coal dust, is allowed to remain in contact withthe rolled steel parts, the acid formed thereby eats into the steelparts.

Such corrosive and acidic action vrapidly eats away the rolled steel andexperience shows that these hoppers and associ ated parts mustfrequently be replaced, which is expensive, not only from material andlabor cost, but also by keeping the car out of service.

An object is to eliminate the cost and delay in fabricating the numerouscomponent parts of the present structural steel car parts.

Another object of forming the car part of cast metal is to eliminatethe,possibility of loose connections which would permit relative vmotionbetween the component parts lof th-e car part, as it is common knowledgethat the vibration of the car in motion, due to rough and uneven track,and steel wheels rolling on steel rails, together with longer trains andhigh speeds in present day practice, cause riveted joints and built-upsections to work loose and the railroads look with favor uponl anydevice which reduces the number of parts and joints as these' are theOriginal application led April 8, 1929, Serial No. 353,494. Divided andthis application filed July 15, 1931.

weak parts of the car and the more such weak parts are eliminated, thelonger the life of the car.

rin object of the invention is to form the parts of the car which comein contact with the lower part of the lading of cast metal to 6, whichsills and cover alate extend between Y the body bolster and usuallytherebeyond to accommodate the draft gear. The side walls may be of atruss or a girder design. In the form illustrated the top (7) Aandbottom (8) chords of the side girder arer connected by the web plat-e 9which also is the load retaining means of the side wall. To meetstrengthrequirements it is preferable to make the top and bottom chords ofrolled steel. In order to save weight and material it is desirable tomake the web plate also of rolled steel.

The car illustrated includes an integral casting comprising a hopper oneach side of the center construction, a center construction hood andpart of a cross bearer. Two of such castings (preferably duplicates) aresecured together to forin the complete hopper part of the car, whichunited castings are then merely secured to the center construction andopposite side walls of the car. Each part of the cross bearer comprisesa web plate 13 with the upper stillener 14 and oppositely disposedsloping lower portions 15 which direct the discharging lading into thehopper. The cross bearer is arranged to protect the lower side chord 8and the lower portion of the web plate 9 from the lading. The crossbearers straddie the center construction 4 and are secured thereto inany convenient manner. We also prefer to cast hinge lugs 16 integralwith this cross bearer to support the hopper door 17. rI`he brace issecured to the side wall and also to the outer end of the cross-bearer12 and comprises a diagonal member 18 extending from adjacent the top ofthe side wall to substantially the middle of the cross bearers. It isalso provided with an extension 19 connected to the upper chord 7 tobrace that member against deflection. The hoppers 2O on opposite sidesof the cross bearer are preferably cast integral therewith. Thesehoppers comprise an inclined portion 21 with oppositely disposedsubstantially upright portions. The inner (22) of said upright portionsis connected to the center sill and arranged to protect it from thelading. The outer (23) of said portions is connected to the side walland arranged to protect the lower chord (8) from the lading. Theintegral reinforcing ribs 24 extend continuously around the inclinedportion and the upright portions of the hopper. The hopper is alsopreferably reinforced with longitudinally extending integral ribs 25below the inclined portion.

The accompanyingr drawing illustrates the preferred form of theinvention, though it is to be understood that the invention is notlimited to the exact details of construction shown and described, as itis obvious that various modifications thereof, within the scope of theclaims, will occur to persons skilled in the art.

This is a division of our co-pending application No. 353,494, filedApril 8, 1929.

We claim:

1. In a railway car, the combination of a center sill, a side wall, across bearer extending between and secured directly to the center silland the side wall, said cross bearer formed of a pair of members securedtogether, each consisting of an integral casting comprising a verticalweb, a downwardly sloping portion extending from said web, and an upperstiffening flange.

2. In a railway car, the combination of a center sill, a side wall, across bearer extending between and secured to the center sill and theside wall, said cross bearer formed of a pair of members securedtogether, each consisting of an integral casting comprising a verticalweb, a downwardly sloping portion extending from said web formed withhinge lugs, and an upper stiifening flange.
